I drink loose leaf tea throughout the day and originally made my own tea bags every morning. I hated the time it consumed and wasted materials. The H2Jo Coffee Filter works beautifully as a tea filter as well. I scroop some tea leaves into my water bottle in the morning and screw on the cap. Then I add boiling water in the office and have a lovely cuppa the whole day.

For all you coffee drinkers, this is also an elegant and inexpensive solution to cowboy coffee or a ridiculous travel french press (so... unitasking). Yes, you may get some small grinds in there but if you are considering a french press, it would do the same, and if you can't grind your own beans (or get them ground to specification) then why are you bothering with a french press at all?

The only con is that my Camelback lid doesn't seem to screw on tightly-- it drips a little so I pour my tea into a mug. I think this could be remedied with a little creativity though. All in all, a great way to reduce waste and improve the quality of my tea (whole leaf is much better than tea bags!)

It also seems to dent easily, but I don't think that really affects the function. Just make sure to keep it in your bottle, not loose in your bag.

I've only used this at home so far, so only gave 4 stars until tried in the wild. I love my morning coffee, but feel the java press with my stove is too difficult to clean. I've tried this with coffee grounds in the Nalgene, worked beautifully, but a little difficult to clean the water bottle with LNT. Also tried with loose tea in the filter, then removed and drank from the nalgene. Seemed to work a little better for me.

this is a great example of the multiple use concept for easing your load. This product stays on my nalgene and acts as a filter when not in use for its design which works awesome. takes up no extra space, adds practically no extra weight and works perfect. all of my friends have converted to this peice of kit after seeing mine in use.

We owned other types of coffee filters, but after seeing the H2JO being used we ordered the H2Jo from EMS. We just came back from a 3 day march hiking trip in the Adirondacks. It worked so well, no having to hold the filter, just add hot water,the filter ad your done!Great coffee on the trail. Simply the best!
